ENDOSPERM PERSISTENCE IN ARABIDOPSIS RESULTS IN SEED COAT FRACTURES AND LOSS OF SEED LONGEVITY


Numerical study on the fracture characteristics and failure mode of hard coal under coupled static and dynamic loads

It has been well accepted by mining researchers that coal tends to undergo abrupt fracture under the coupling effect of dynamic and static loads.Hence, the study of influence Sealed Beam Conversion Assembly of coupled static and dynamic loads on coal failure behaviour is meaningful for the understanding of coal burst.In this paper, PFC modelling of
